Improved pressurization system for abrasive supply pot

Abstract From the Canadian patent

A novel supply pot for holding a, particulate abrasive is provided which greatly reduces the amount of moisture which is contained therein during pressurization. The supply pot includes a compressed air piping which directs compressed air from a source of compressed air to an inlet piping to the supply pot and to a downstream inlet to a blast hose, the compressed air piping comprising a moisture diverter which directs the compressed air from the piping to the blast hose initially bypassing the inlet to the supply pot the, diverter allowing backflow of compressed air from the outlet thereof to the inlet to the supply pot.
